Many years ago, I purchased a used Ruger Super Blackhawk. After a short time, I realized that the front sight had been silver soldered on at an angle. I just adjusted the rear sight to compensate. Was not overjoyed with it that way, but learned to live with it. I often wondered how that could happen. Certainly they use jigs and fixtures to keep things straight while Silver Soldering on the front sights.
Before someone suggests that the sight may have been bent, the sight blade and the base were integral, the base was definitely soldered on at an angle.
